摘要： A linear synchronous motor is provided, of which a core unit may readily be manufactured. Accordingly, the manufacturing cost of the linear synchronous motor may be reduced, and the weight of the linear synchronous motor may be lightened. The linear synchronous motor includes a frame member that is formed of a magnetic conductive material and surrounds the periphery of a core unit centering on a shaft. The frame member functions as a yoke that magnetically connects a plurality of magnetic pole portions. The frame member is constituted from a first divided frame member and a second divided frame member fixed to the core unit with screws.

The permanent magnet rods each have a magnetically permeable shaft and a permanent magnet row having a plurality of permanent magnets so arranged that opposite polarities of their magnetic poles alternately appear. The permanent magnet row of the permanent magnet rod is arranged with a positional difference of 180° in an electrical angle from the permanent magnet row of the permanent magnet rod. The second unit that constitutes a moving member includes unit cores and winding sets arranged alternately in an axial direction of the shaft. The winding set includes two excitation windings through each of which the permanent magnet rod loosely extends. One excitation winding of the winding set is excited with a phase difference of 180° in an electrical angle from the other excitation winding.
